Fig. 2

Seed morphology, seed weight, and starch granule morphology. Photos of dehulled mature seeds of the wild type (WT), be1 and be2b single mutants, and be1 be2b double mutant were captured under light from above (a) and beneath (b). Numbers above the photos indicate mg of seed weight. Data represent mean ± standard error (SE; n = 50). Values in parentheses indicate the percentage of seed weight relative to the WT rice cultivar Kinmaze. Significant difference between be2b and be1 be2b are indicated with an asterisk (*P < 0.05; Student’s t-test). (c) Morphology of a purified starch granule observed by scanning electron microscopy. Scale bars: 5 μm
